That’s a wrap for CityJS Athens! 🎉 Three days, including one dedicated to fun!

Huge thanks to our Greek & international speakers for sharing insights on development & AI. Some attendees called it our best Athens event yet, your talks and hard work made it happen! 💛 #CityJSAthens

@ErasmoHernandez Top man at upper town

[Maximilian @maxedapps]

It was amazing!

[Maximilian @maxedapps]

It’s raining today but the last few days at @cityjsconf Athens we’re just amazing!

Truly had a blast, met many amazing people, and hopefully was able to share some optimism with my closing keynote about adopting to a new reality as a dev. 🙂

Thanks for having me!

[Erasmo Hernández @ErasmoHernandez]

Developers having fun in Athens instead of vibe coding JavaScript applications 🇬🇷

Leaving @cityjsconf with nothing but gratitude.

I was able to hang out with very cool people, got inspired a lot and had amazing conversations (sadly forgot to take a selfie from my talk).

On my way back, I also had a nice surprise upgrade to business class (thanks @TurkishAirlines) so I can say my overall experience was reminding me how lucky and grateful I am to do this job! 🙌🙌

Omw to @cityjsconf Athens! 💪

[CityJS Conference | Athens 21-23 October @cityjsconf]

Hands-on at Epignosis in Athens with @DavidKPiano ! 🚀

“Graph Engineering: Making State-Machine Powered Agents” explores TypeScript and XState to make agent states explicit, plan recovery paths, and visualise execution.

Then simulate the paths—without making LLM calls.

[CityJS Conference | Athens 21-23 October @cityjsconf]

Great start at Kaizen Gaming with @tpiros ! 📸

Signature Tamas selfie first, then a hands-on AI agents workshop in TypeScript.

One agent, one tool, and the loop that makes it work: perceive, decide, act, repeat.

Time to build! 🚀
